Warren Buffett’s Strategy for Making Retirement Savings Last
Preparing for retirement remains a serious challenge for Indonesians. The Financial Services Authority (OJK) said pension-fund literacy in 2026 had reached only 22.21 per cent, while inclusion stood at just 5.10 per cent. The low figures highlight the difficulty many people face in understanding and using financial products to prepare for life after work.
The issue is not simply how much money people manage to accumulate during their working years, but also how to maintain their financial capacity once regular income stops.
The OJK records Indonesia’s post-retirement income replacement ratio at around 15–20 per cent, well below the 40 per cent benchmark cited by the authority.
The replacement ratio compares a person’s income after retirement with their earnings before retirement. A low ratio points to a gap between income during working life and income in retirement.
The OJK presented the figures during the Indonesia Pension Fund Summit (IPFS) 2026, held in Jakarta on 24–25 September 2026.
OJK Board of Commissioners Chair Friderica Widyasari Dewi stressed the importance of strengthening the pension system, as the demographic structure changes and life expectancy rises. She made the remarks at the forum’s closing on Friday (25 September 2026).
Friderica said strengthening the pension industry should not focus solely on asset growth and participant numbers. The pension benefits people receive must also be considered so they can maintain a decent standard of living after they stop working.
“Our future agenda cannot focus only on industry growth,” Friderica said, according to an OJK press release dated 25 September 2026.
She also warned that retirement planning should begin when people enter the workforce, rather than when retirement is already approaching.
The OJK’s warning makes the wealth-management strategy long practised by legendary US investor Warren Buffett worth examining. Buffett has long emphasised long-term investing, ownership of productive assets, keeping investment costs down and maintaining relatively safe instruments to withstand market volatility.
These principles offer one approach to the risk of running out of money in retirement, although no investment strategy can eliminate that risk entirely.
Buffett’s strategy: 90 per cent shares, 10 per cent bonds
One of Buffett’s clearest explanations of his financial strategy appeared in his 2013 annual letter to Berkshire Hathaway shareholders.
In the letter, dated 28 February 2014, Buffett outlined instructions for managing the inheritance he had set aside for his wife.
“Put 10 per cent of the cash in short-term government bonds and 90 per cent in a very low-cost S&P 500 index fund,” Buffett wrote.
Buffett specifically recommended an index fund from Vanguard, the US investment management company, because of its low fees.
The S&P 500 is a stock-market index that tracks the performance of around 500 large companies listed in the United States. Investing through a fund that follows the index gives investors exposure to many companies at once, without having to select individual shares.
Buffett believes a simple, low-cost investment strategy has the potential to deliver better long-term results than many high-fee, actively managed investments.
But the notable point is not only that Buffett put most of the money into shares. He also deliberately kept part of it in short-term government bonds.
Buffett explained the reasoning in an interview with Becky Quick on CNBC’s Squawk Box on Monday, 3 March 2014.
In the interview, recorded in Omaha, Nebraska, Buffett said short-term government bonds could help cover expenses when the stock market falls sharply.
He described a situation in which his wife might need to withdraw around 3 or 4 per cent a year to meet living costs. If the stock market were going through a difficult period, she could draw on the bond allocation, avoiding the need to sell shares while their prices were falling.
The strategy shows that retirement wealth management is not only about seeking returns, but also about ensuring that funds are available for expenses without having to sell riskier assets at an unfavourable time.
Even so, the 90 per cent shares and 10 per cent government-bond allocation was designed by Buffett for managing his family’s inheritance. It is not an investment formula that automatically suits every retiree.
